Question
Two rods of the same weight and equal length have different thickness. They are held vertically on the surface of sand as shown in Figure Which one of them will sink move? Why? 
✓
Answer
As we know that pressure exerted by the body is inversely proportional to the area where force is applied. So, the thinner rod, i.e. rod B will sink more because it has less area of cross-section in contact with the surface, hence it will exert more pressure on the sand with respect to the rod A.
